BlownFiveLiter have car, will race....wait, it doesn't run 15 Year Member Nov 29, 1999 3,133 18 108 Chicagoland Sep 2, 2007 #2 Sep 2, 2007 #2 I don't believe it'll work without notching the pistons. The lift with 1.6 rockers is .499/.510, so with 1.7's it'd be .530/.542. Either one of those would be too much for stock pistons.
